Sun were always a bit wary about the Java trademark after their tangle with Microsoft. That may be part of the issue, but honestly I think it's more likely to be down to the random bureaucracy of the JSR and JCP efforts.

I really don't buy the conspiracy theory and I'm puzzled to see the article up-voted so high without comment.

I'm much more interested in the question of what will actually arrive in Java/JDK7 and whether they'll ever move to a faster release cycle than the current geological process.
